Abstract

A lead is connected to the electrode plate of the power generating element, and exposed externally from the deposited portion of a battery case. The portion of the lead crossing film edges is covered with two flat insulating covering resins which are thermally deposited to each other. At this portion, the covering resins and film edges are thermally deposited to each other. The covering resin is composed of two layers of an outer layer and an inner layer. At least the outer layer is colored and crosslink-coupled by irradiation of electron beams. The outer layer has a higher softening point than the inner layer.
